Singer-actor Seo In-guk has been cast in SBS’s new drama, his agency said today.

Seo will be joining actress Kong Hyo-jin and So Ji-sub in romantic comedy horror “Sun of the Lord” [translated title] which is set to air in August, Jellyfish Entertainment said through a press release.

Set in a hotel, the drama centers on a greedy boss and a dismal female personal assistant who will console souls with scary yet sad stories. Here, Seo will take the rigid and manly role of a head of the security of shopping mall Kingdom.

The production company, Bonfactory, was quoted in a statement as saying that Seo was cast because of his colorful character of being soft and manly at the same time. Seo will be showing a new side of him through the upcoming show.

The drama will be written by the ‘Hong Sisters,’ namely Hong Jeong-eun and Hong Mi-ran, who have written several smash hit dramas including SBS’s “You’re Beautiful” and MBC’s “The Greatest Love” while producer Jin-hyuk who directed Lee Min-ho’s SBS hit drama “City Hunter” and Lee Seung-gi’s “Brilliant Legacy” will take the megaphone.

Meanwhile, Seo is currently shooting his upcoming sports film “No Breathing,” which cranked in on May 19, with rookie actor Lee Jong-suk and Girl’s Generation’s Yuri.
